DETACHABLE GRAIN-DRILL SHOE.

SPECIFICATION forming part Of Letters Patent No. 643,435, dated February13, 1900.

Application filed August 23, 1899. Serial No. 728.250. (N0 model.)

To ctZZ whom it may concern;

The invention consists, further, in the constructions and combinationshereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of a grain-drill shoe embodying my invention. Fig.2 is a plan view of the same. Fig. 3 is a vertical central section online a: a; of Fig. 2.

In the drawings, 2 represents the hollow shank of the shoe, throughwhich the grain is dropped by the feeding mechanism of the drill. Thisshank is of the usual or any preferred size and form. A drag-bar 3,consisting of two members preferably arranged a short distance apart,has its rear end riveted or otherwise secured to the lower end of theshoe-shank 2.

The shoe 5 is made separate from the hollow shank 2 and is provided withmeans for readily attaching it to the shank and dragbar. The shoe 5 isof the usual form, having an open-ended recess into which the grainfalls from the hollow shank and out of the rear end of which the grainpasses in the usual manner into the drill made by the shoe. Any suitablemeans may be employed for detachably securing the shoe to the drag-barand shank. As here shown, the two members of the guide-bar areseparated, being held apart by a suitable plate or bar 7, which is heldin place by rivets 9, which pass through the two members of the drag-barand through said plate. The shoe is provided at its forward end with aprojection 11, having a recess in its upper end adapted to engage a pin15, extending between the two members of the dragbar. Near the rear endof the shoe is a projection 17, secured to the shoe by a bolt or rivet19. The upper end of the projection 17 is provided with a hook 21.- Aneccentric locking-lever 23, provided with a pin 25,'is adapted to engagethe hook on the projection 17. By turning the lever from the positionindicated in full lines in Fig. 3 to the position indicated by fulllines in Fig. 1 the shoe is drawn firmly against the under side of thedrag-bar and is firmly locked into position. I may also provide aprojection 29 on the lower end of the hollow shank 2, that extends intothe recess in the shoe, as shown in Fig. 3, and helps to hold the shoein proper position.

The entire shoe, it will be seen, is readily detachable and may asreadily be replaced. If the shoe becomes dull, it may be taken off andground or sharpened and replaced. No tools are necessary either forremoving or replacing the shoe. If a shoe becomes broken, a new one maybe substituted therefor.

I do not limit myself to the particular devices shown for detachablysecuring the shoe in position, as the same may obviously be varied inmany particulars without departing from my invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with a grain-drill-shoe shank anddrag-bar, of a removable shoe and means for detachably securing saidshoe to said shank and drag-bar, for the purpose set forth.

2. The combination, with a hollow graindrill-shoe shank, of a shoe andmeans for detachably securing said shoe to the lower end of said shank,for the purpose set forth.
